Unfortunately, it seems that the latest iPad 3.2 OS is not compatible with iOS 4.0 which is what Dapp 1.2 had to be built with to support the iPhone 4 retina display.

Just waiting for the Apple Event today, hopefully they announce iPad OS 4.0.  If not, then I’ll have to roll back Dapp to 3.1.3 OS which means Live Preview gets to stay but the retina display support will no longer work.  As such, when Dapp 1.2.1 is available, this will be an optional upgrade for those using iPhone 4 devices.
